1. Homework Statement
A 17.89 cm diameter, 42.43 cm tall steel cylinder (rsteel=7900 kg/m3) floats in mercury. The axis of the cylinder is perpendicular to the surface. What length of steel is above the surface?
2. Homework Equations
Pb=Pa+density*g*h
3. The Attempt at a Solution
Pa=101300
Pb?
density= 7900 kg/m^3
H=(total length-submerged)
g=(9.8)
Pb=101300+((9.8*7900*(total length-submerged))
I have 2 unkowns. What would Pb be?
